O(αs2) polarized heavy flavor corrections to deep-inelastic scattering at Q2 ≫ m2
Nuclear Physics B, 2023 We calculate the quarkonic O(αs2) massive operator matrix elements ΔAQg(N),ΔAQqPS(N) and ΔAqq,QNS(N) for the twist–2 operators and the associated heavy flavor Wilson coefficients in polarized deeply inelastic scattering in the region Q2≫m2 to O(ε) in the

Physics Letters B, 2020 We study the semi-inclusive production of real, high-pT, isolated photons in unpolarized and polarized lepton-proton collisions, ℓp→ℓγX. In particular we analyze the transverse nucleon single-spin asymmetry within the collinear twist-3 formalism in ...

Multi-jet merging with TMD parton branching
Journal of High Energy Physics, 2022 One of the main theoretical systematic uncertainties in studies of final states with large jet multiplicities at high-energy hadron colliders is associated with the merging of QCD parton showers and hard-scattering matrix elements. We present a method to

Quarkonium TMD fragmentation functions in NRQCD
Journal of High Energy Physics, 2020 We study the transverse-momentum spectrum of quarkonium production from single light-parton fragmentation mechanism. In the case of semi-inclusive deep inelastic scattering, we observe that there are two possible initiating processes, namely photon-gluon

A NOVEL COUPLED T-MATRIX AND MICROWAVE NETWORK APPROACH FOR MULTIPLE SCATTERING FROM PARALLEL SEMICIRCULAR CHANNELS WITH ECCENTRIC CYLINDRICAL INCLUSIONS [PDF]
Progress In Electromagnetics Research, 2005 Abstract—A novel coupled T-matrix and microwave network approach is proposed for the multiple scattering from parallel semicircular channels. First, an equivalent network is set up to derive the T-matrix of a single channel, in which the S-parameters are derived for the semicircular boundary and the T-matrix of the inclusive cylinders is served as ...

Scattering Characteristics of a Partially Debonded Compliant Inclusion-Matrix Interphase
, 1990 Scattering characteristics have been calculated for a spherical inclusion with partially debonded interphase conditions. Three scattering characteristics of the scattered field have been selected for investigation: 1) the frequency response at a fixed point, 2) the scattered field at a fixed frequency along an observation line, and 3) the radiation ...

J/ψ meson production in SIDIS: matching high and low transverse momentum
Journal of High Energy Physics, 2020 We consider the transverse momentum spectrum and the cos 2ϕ azimuthal distribution of J/ψ mesons produced in semi-inclusive, deep-inelastic electron-proton scattering, where the electron and the proton are unpolarized.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
